Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 and remember the name of your Lord, morning and evening; 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Surely men love what hastes away and forget the grievous day (ahead). 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 But you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
